145. The di-lepton physics program at STAR

Lijuan Ruan (Brookhaven National Laboratory)

01/06/2012, 09:00

Oral presentation

Di-leptons are ideal probes of the strongly interacting hot, dense medium created at RHIC. They are not affected by the strong interaction once produced, therefore they can probe the whole evolution of the collision. In different mass regions, di-leptons can be used to probe vector meson in-medium modifications, Quark Gluon Plasma (QGP) thermal radiations, and color-screening features of...

166. Electromagnetic Radiation probing the Space-Time Evolution of Heavy ion collisions

Axel Drees (Stony Brook University)

01/06/2012, 09:30

Oral presentation

Over the past years PHENIX has published multiple results on electron-positron pairs and direct photons from Au+Au collisions, which reveal a number of puzzling and not understood features. First measurements of direct photons at momenta below 3 GeV point towards a significant thermal yield consistent with initial temperatures well above the transition temperature. However, this thermal source...

167. Characterizing energy loss in ALICE

Peter Jacobs (Lawrence Berkeley National Laboratory)

01/06/2012, 10:00

Oral presentation

This talk will present a global view of what has been learned to date from ALICE data about the interaction of jets with the hot medium generated in high energy nuclear collisions at the LHC. The discussion will incorporate measurements of inclusive charged and identified hadrons, hadron correlations, heavy flavor measurements, and first ALICE measurements of fully reconstructed jets,...
